DNG export to JPG - missing EXIF data

Hello,

I have a problem with the LR6 while I exporting DNG files to JPG. Even if DNG file has exif data and they are shown and recognized in LR6 without any problem, the exported JPG from the DNG has nothing in EXIF. EXIF metadata are completely empty. If I made export to JPG from the RAW file, before converting it to DNG, there is no problem at all. Also DNG file converted from the RAW file has all the EXIF metadata. It is really strange that the EXIF metadata are lost. I was trying to change any related LR6 settings, optimize catalog, ... but nothing helped. I'm using Windows 10 PC machine. Any idea how to fix it?

Thanks.

    Here is the link to the Dropbox where are the original CR2 file, DNG from DxO and finaly exported JPG files.

    Dropbox - LR6

    Hope that this will help.

    I suspect the problem is that the DNG wasn't properly constructed. Exiftool (the most authoritative tool for examining metadata) reports the following:

    This is a common problem -- software tools forget to adjust the MakerNotes (due to a poor design of the standard).  I tried fixing it with Exiftool, but Exiftool can't always do it 100% correctly.  

    It is a little curious that LR is able to read the DNG's metadata when it is imported into the catalog, but not when it exports the metadata -- but that's the nature of bugs.  If you paid for DxO, you should file a bug report with them.

    Yes, I have selected "All Metadata" in export dialog. Even if I export both files at once to ensure that the export setting are the same for RAW and DNG, the resulting JPGs are different. JPG from RAW has all EXIF metadata, but JPG from DNG not.

    To troubleshoot this most effectively, please upload to Dropbox (or similar) the original raw, the DNG, and the JPEG exported by LR from the DNG, and post the sharing link here.

    Can you confirm that when exporting the DNG you have "All Metadata" selected in the Metadata box of the Export dialog?

    I'm going to reply here to your other question.

    May I ask why the check boxes are of importance to you.

    I just took some images and imported them and got a check box next to the folder that will be created during the import. I am on Win 7 Pro with the most recent LR version, CC 2015.7.


    I didn't think that it is so much important but useful and it is a software issue. In my case I have big memory card (128 GB) and it is a bit annoying when you want import only new files but you still have older files on the card and such check-boxes disappearing after clicking on them. See the video here 2016-08-09 23h24_27.mp4 - Google Drive and after each click I have to use ALT+TAB to switch to some application and back to LR6 and check-boxes are back, until next click. Previous version LR5 haven't such issue. It seems like issue with refreshing the view after click on picture/folder check-box. I'm running on Win 10 x64 Pro and stand alone LR 6.7.
